Wet Scrubbing: Configurations - Venturi Scrubber

Designed to suit any process gas requiring particulate removal, the MikroPul Venturi scrubbers classic single venturi design offers maximum scrubber efficiency through the simple four stage unit.

Operation

The design of the MikroPul Venturi Scrubber consists of a "wet approach" venturi followed by a liquid entrainment separator. Dust laden gases enter the venturi and instantly make contact with the tangentially introduced scrubbing liquid swirling down the venturis converging walls.

At the venturi throat, the gas and liquid streams collide and the liquid breaks down into droplets which trap dust particles. This gas/liquid mixture passes through a flooded elbow, and enters the entrainment separator through a tangential inlet. Centrifugal action removes the heavy wetted particles from the gas stream. As an alternate, when very large diameter separators are required, the liquid is separated by passing the stream through a chevron-type mist eliminator baffle.

The dust/liquid mixture is discharged from the separator bottom drain and the cleaned gas leaves through the top of the separator.
